Know where a file came from, and what it says, before you share it

Every photo, PDF, song and video carries a second layer of information you never see on screen. A phone photo records where it was taken. A PDF keeps the name of whoever made the template. A video stores the phone model and the second you pressed record. An AI image can hold the prompt you typed and a signed record of the tool that made it. Toolvy’s AI and privacy tools read that layer to help you judge whether a file was made with AI, show you everything else it reveals, and remove what you choose — all in your browser, so the file is never uploaded. Open your browser’s Network tab while you work and you will see no request carrying it.

Was it made or written with AI?

The AI detector checks images, videos, PDFs, Word files and text, and shows two kinds of evidence side by side. File evidence is what the file declares: Content Credentials signed by OpenAI, Adobe, Google or a camera maker, IPTC AI labels, AI tool names and embedded prompts. The second check runs on your device and reads the content itself: a visual classifier scores the picture — five regions of an image, eight frames of a video — and a text classifier scores the writing in a document, passage by passage. For photos and art, use the AI image detector; for clips from tools such as Sora and Veo, the AI video detector; for essays, PDFs and Word files, the AI text detector. No detector is certain: AI-text detectors in particular misjudge short, formal and non-native English writing, and a missing AI signal doesn’t prove a file is real. Treat the verdict as evidence to weigh — never, on its own, as grounds to accuse anyone.

See everything a file reveals

The metadata viewer lists everything it finds in six groups — AI & provenance, location, device, people, software & dates, and other — and decodes C2PA Content Credentials into plain words: which tool signed the file, what it did and what kind of media it is. Copy the report, or remove the lot in one click.

Remove AI labels, or remove everything

The AI metadata remover and the C2PA remover open in “AI & provenance only” mode: they strip Content Credentials, IPTC AI labels, generator tags and embedded prompts, and keep your camera details, copyright and location. Switch to “Everything” for a completely clean file. Neither touches invisible watermarks such as SynthID — those live in the pixels, not the metadata — and neither changes what platforms expect you to disclose.

Documents, video and audio

The PDF metadata remover rewrites a PDF without its author, title, creator app, dates, XMP and document ID, leaving every page as it was. The video metadata remover strips GPS, recording date, device details and telemetry tracks, and the audio metadata remover clears ID3 tags, comments and cover art — both with a stream copy, so nothing is re-encoded. For a quick photo-only clean-up, the EXIF remover strips GPS and camera data from a picture.

Lossless, and checked

Images lose their metadata at the byte level, so the pixels are bit-for-bit identical; the color profile and orientation flag stay, so a photo looks and sits exactly as before. Every output is inspected again before you download it, so you see what remains instead of hoping it worked.

Common questions

AI & Privacy tools, answered.

The questions people ask before trusting a browser tool with their files.

01

Can these tools tell whether something was made or written with AI?

They can give you evidence, not proof. The AI detectors read what a file declares — signed Content Credentials, AI labels, AI tool tags and embedded prompts — then run on-device checks: a visual check on images, video frames and photos inside PDFs, and a text check on the writing in PDFs, Word files and pasted text. Platforms often strip metadata, so a file with no AI signal may still be AI-made.

02

How accurate is the AI detector?

Signed Content Credentials that declare AI are its firmest answer. The visual check is an estimate: on its developer’s own development data it reached 90–96% balanced accuracy and flagged about 3–5% of real photos as AI — not an independent benchmark. It is weaker on small, compressed or partly edited images, and video results are experimental. For writing, the text model’s developer reports 90.17% of AI text caught at a 1% false-positive rate on the RAID benchmark; real-world accuracy is lower, and short, formal or non-native English writing can be wrongly flagged.

03

What is hidden metadata, and why remove it?

Metadata is information stored inside a file about the file: where a photo was taken, which phone or camera recorded it, who wrote a document, which software touched it and when, and whether an AI tool made it. It travels with every copy you send, so removing it before you share keeps those details to yourself.

04

Are my files uploaded to a server?

No. Every tool here runs in your browser: files and pasted text are checked, inspected and cleaned on your own device and never uploaded, which you can confirm in your browser’s Network tab. The AI detector’s ~44 MB visual model, its ~126 MB text model and the ~10 MB audio and video engine each download once, on first use, and are then cached.

05

Does removing metadata reduce quality?

No. Image metadata is removed at the byte level, so the pixels are bit-for-bit identical; the color profile and orientation flag are kept so photos look and sit the same. Audio and video are stream-copied without re-encoding, and PDFs are rewritten with every page untouched.

06

Will removing AI metadata remove an “AI info” label?

It removes the metadata those labels read — C2PA Content Credentials, IPTC AI labels, generator tags and prompts — so a new upload no longer carries those signals. It does not touch invisible watermarks such as SynthID, which platforms can still detect, and it does not change any duty to disclose realistic AI content.

07

Can I remove the author and other properties from a PDF?

Yes. The PDF metadata remover rewrites the file without its Title, Author, Subject, Keywords, creator app, dates, XMP, app-private data, comment author names and old saved revisions, and replaces the document ID — without changing a page. Password-protected PDFs need unlocking first.

08

Which file formats are supported?

Images: JPEG, PNG, WebP, GIF, AVIF and HEIC/HEIF. Documents: PDF, plus Word (.docx), plain text and Markdown for AI-text checks. Audio: MP3, WAV, FLAC, M4A/AAC, OGG and Opus. Video: MP4, MOV, M4V, WebM, MKV and AVI. The AI detectors take images, video and documents, or pasted text; the removers take images, PDFs, audio and video, and can clean many files at once, downloaded singly or as a ZIP.
